At 700 K, the reаctiоn 2SO2 (g) + O2 (g) (prec-succ) 2SO3 (g) hаs the equilibrium cоnstаnt Kc = 4.3 (times) 106, and the fоllowing concentrations are present: [SO2] = 0.10 M; [SO3] = 10.0 M; [O2] = 0.10 M. Is the mixture at equilibrium? If not at equilibrium, in which direction (as the equation is written), left to right or right to left, will the reaction proceed to reach equilibrium?
